| Abstract(in English) | Wavelength division multiplexing (WDM) technologies have become indispensible for high capacity optical communication systems, and are used not only in subscriber networks but also in long-haul communication (e.g. in submarine cable systems). However, the capacity of the long-haul WDM systems is restricted by several factors as follows : (i) gain bandwidth limited by the self-filtering effect (ii) optical fiber nonlinearities, and (iii) excess of accumuleted chromatic dispersion. We have evaluated techniques required for long-haul WDM transmission. The transmission of eight-channels 2.5Gbit/s WDM signal over 12000km was successfully confirmed with the additional gain equalizer for accumulated imperfect gain flatness of the repeaters, and chromatic dispersion management (with chromatic dispersion compensation before transmission) |
